Texture

Action : “texture”

Method : “texturing”

Texturing consists in associating each simplex of the surface to a part of an image.

To apply a georeferenced texture to our mesh, we use inverse RPC to get the image coordinates of each point of the cloud.

Warning

If OpenGL is used in the back to display the texture, one needs to normalize the image coordinates between 0 and 1. Otherwise, over 1, it is interpreted as a duplication of the texture. The code makes this normalization.

In the current version of the code, occlusions are not handled; neither are multi-image textures. Some limitations come from the file format on which to serialize the mesh which does not handle it. File format and texture should closely be considered.

Note

Currently, the code uses an independent implementation of RPC. It could be replaced by any other application (ShareLoc, LibGeo, etc.).

Warning

The current implementation of RPC is Pleiades oriented. One should check the tools/rpc code and modify it for other data.
